Castle 1717 motor with free water jacket

[Brushless55]

The air version has air holes in the front of the motor, but most significant difference is the can, it has two flat spots milled into the fins. Whether or not the water jacket will fit without leak is the big issue!

so the water jacket could have an issue on this motor?

[Rumdog]

Definately will not work! KV is a little diff. too

[Brushless55]

I was just going to say the kv is 80 less
but wouldn't the cooler work just fine?

[JMSCARD]

No it won't work look at the flat spots on the finned can.... That's what the "O" ring sits on... Looks to me like it would t be worth trying.... I am sending mine back and getting the right motor... Also there is something about the wiring too... Apparantly you can't shorten the motor leads either... Not that I would want to but here are several differences... Plus I want 1580kv as I want to spin a big prop on 5s2p... That last 80kv I want!! Lol:):)

You must not be seeing that flat spot??? Its not a round can so no, the o rings wouldnt work.

the fins are ground to the can not the can ground with a flat spot
so if the o-rings seat to the can it should work, but if it needs the fins to seal then it will not work
and the fins are not 100% ground to the can, there is just a small amount left on the two sides

[old guy]

would this work in a 1/10th scale twin wing 1717-1580KV

I guess maybe you could machine ALL the cooling fins off and use a leopard jacket or something...I dont think anyone makes a jacket that seals between the fins though.

I think you could make a jacket work, but you would have to jb weld or something where the flat spot meets the oring. Or a real thick bead of RTV around the oring.

I just got an email saying "all orders made in the last 7 days will be shipped by 10/01/2010"

Yeah not surprising. The sound of people chatting was quite high when I talked to them and there were several interruptions during conversation. I'd say they are BUSY!

Still, it's worth waiting a week for such a deal IMO.


BTW- the flat spot in the fins will cause the O-ring to roll and will tear as you're slipping the can on. The fins hold the small o-rings in place. There's no way to hold them while they are being compressed during installation. They will just roll and tear.

Ask me how I know.

Ha ha... the extra 80kv are gonna get me just that little bit more rpm... I currently run my mean machine on a 1500kv 1515 1.5y on 5s mostly.... so I am going to use a larger prop with the 1717 and spin the prop 1680 more times a minute too...lol..

Oh man!
a 1717 in a Mean Machine
maybe I should try one of the 1520's I bought and run it in my Mean Machine on 5s2p
